historyMode

historyMode
Displays the mode of the field replaceable unit (FRU) history log.
Synopsis historymode
Description Use this command to display the mode of the history buffer, which records the insertion and
removal of FRUs on a switch or chassis.
This command supports two modes of handling new log entries once the history buffer has
reached its maximum size:
Rotating mode
First-in mode
The history mode is a factory setting that cannot be changed by the end user. The size of the history
buffer depends on the HW platform: The Brocade 48000 Director supports 100 history log entries.
The Brocade DCX backbone supports a maximum log size of 50 entries. Since the WWNs are
completely separate FRUs in the DCX, they have redundant data in these units. All other platforms
containing FRUs support 28 history log entries.
Note The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
